android saving a value from a textview

Question

I made a simple counting app where there is Text-view that contains the counted number, and I want to save the counted number so that when I close the app the counted number should be there.

You should use SharedPreferences. Save the count to preference every time it is updated. Read and load the saved value in TextView when app starts next time.

The best solution for your problem is to use SharedPreference. create another class called SaveCounterValue and copy the following code to that class

public class SaveCounterValue {

static final String PREF_COUNTER= "counter";
static SharedPreferences getSharedPreferences(Context ctx) {
    return PreferenceManager.getDefaultSharedPreferences(ctx);
}

public static void setCounter(Context ctx, int counter)
{
    SharedPreferences.Editor editor = getSharedPreferences(ctx).edit();
    editor.putInt(PREF_COUNTER, counter);
    editor.commit();
}

public static Long getCounter(Context ctx)
{
    return getSharedPreferences(ctx).getInt(PREF_COUNTER, 0);
}

}

Then in your activity after conter++ you copy the below code

SaveCounterValue.setConuter(context, counter);
